Balance coil type fuel sender

hi,

I've just bought a tank with the tube type balanced coil sender in it. I've stuck a multimeter across the positive spade and earth and filled the tank. The reading is changing but it's from about 5 to 8 Meg ohms. I would have expected in the 0- 200 ohms but have never measured this type of sender. Anyone got experience in them


Cheers

No-one with this type of sender that's checked the resistance?

 

That does seem odd - I would've expected a few hundred ohms as well. Where are you measuring it?

 

On the positive terminal to the earthing terminal. Using ohms law the current would be micro amps..... I think it's faulty, strange as it rises and falls when I filled and emptied the tank with a hose pipe?

 

Does seem weird

I'm sure now the values are suspect. I have ordered a new unit and I will test that when it comes. Parts cost keeps on rising!
